ZnO nanoparticles doped with aluminum (AZO nanoparticles) were investigated using low temperature thermoluminescence (TL) and structural characterization experiments. TL experiments were performed on AZO nanoparticles in the temperature range of 10-300 K. TL curve presented one intensive peak around 123 K and two overlapped peaks to intensive peak around 85 and 150 K for heating rate of 0.1 K/s. Curve fitting and initial rise methods were used to find the activation energies of associated trapping centers. Analyses resulted in the presence of three centers at 0.05, 0.08 and 0.17 eV with peak maximum temperatures (T-m) of 86.2, 121.5 and 147.1 K, respectively. TL experiments were expanded using different heating rates between 0.1 K/s and 0.5 K/s. Behavior of revealed traps was investigated using an experimental technique called as T-m - T-stop method. It was seen that traps are quasi-continuously distributed within the band gap. Structural properties were studied using x-ray diffraction, energy dispersive spectroscopy and scanning electron microscopy experiments.

Dielectric and piezoelectric properties of PZT ceramics doped with strontium and lanthanum
Kalem, Volkan; Çam, İbrahim; Timucin, Muharrem (Elsevier BV, 2011-05-01)
PZT based piezoelectric ceramics obtained by doping with various levels of Sr2+ and La3+, designated as PSLZT, were prepared by conventional processing techniques. The effects of Sr2+ and La3+ additions, and that of the Zr/Ti ratio on microstructure, on phase constitution, and on the dielectric and piezoelectric properties were investigated. XRD data revealed that all PSLZT compositions had perovskite structure in which increasing Sr and/or decreasing Zr/Ti ratio increased the tetragonality. In PSLZT cerami...
Hydrothermal synthesis of Yb-doped BiFeO3 crystallites and their structural, magnetic and electrical properties
Özdilek, Çağrı (Elsevier BV, 2020-01-01)
© 2020 Elsevier Ltd and Techna Group S.r.l.The influence of Yb doping on the structural, magnetic and electrical properties of bismuth ferrite (BiFeO3) was investigated. Well-crystallized BiFeO3 (BFO) and Yb-doped BiFeO3 powders (Bi1-xYbxFeO3: x = 0, 0.03, 0.05, 0.1) were successfully synthesized via a typical hydrothermal method. X-ray diffraction (XRD) revealed that powders have a distorted rhombohedral structure with a space group of R3c. Field emission scanning electron microscope (FESEM) studies indica...
Characterization by Fourier transform infrared spectroscopy of hydroxyapatite co-doped with zinc and fluoride
Uysal, I.; Severcan, F.; Evis, Zafer (Elsevier BV, 2013-09-01)
Pure and Zn2+ and/or F- doped hydroxyapatite (HA) were synthesized by the precipitation method and detection of ion incorporations into the HA structure was investigated by a non invasive Fourier transform infrared (FAR) spectroscopic technique. The synthesized materials were sintered at 1100 degrees C for 1 h. The Zn2+ addition amount was kept constant at 2 mol% whereas F- amount was changed. The weight fractions of the HA and CaO were calculated by Rietveld analysis by using GSAS. Co-doping of Zn2+ and F-...
Facile control of hydroxyapatite particle morphology by utilization of calcium carbonate templates at room temperature
Oral, Çağatay M.; Çalışkan, Arda; Kapusuz, Derya; Ercan, Batur (Elsevier BV, 2020-09-01)
Hydroxyapatite (HAp, Ca-10(PO4)(6)(OH)(2)) particles are widely used in orthopedic applications due to their chemical resemblance to the inorganic component of bone tissue. Since physical and chemical properties of HAp particles influence bone regeneration, various synthesis techniques were developed to precisely control the particle properties. However, most of these techniques required high reaction temperatures, which limited the spectrum of obtained HAp particle morphologies. In this study, ellipsoidal,...
Electrochemical polymerization of 9-fluorenecarboxylic acid and its electrochromic device application
Bezgin, Buket; CİHANER, ATİLLA; Önal, Ahmet Muhtar (Elsevier BV, 2008-09-01)
Poly(9-fluorenecarboxylic acid) (PFCA) was synthesized by electrochemical oxidation of 9-fluorenecarboxylic acid (FCA) using a mixture of nitromethane and boron trifluoride diethyl etherate as the solvent and tetrabutylammonium tetrafluoroborate as the supporting electrolyte. An insoluble and conducting brownish-orange film was deposited on the electrode surface, both during repetitive cycling and constant potential electrolysis at 1.15 V. Characterization of the polymer film has been carried out using Four...
